Re: /home as a symlink?
You could run into issues where the value of 'pwd' does not equal the value of 'readlink -f .'. For myself, I use autofs with autohome. It's been a while since I've looked at the details, but I believe it simply does with bind mount described elsewhere in this thread. My main machines happen to be down at the moment, so I can't provide a working example. Outside of that, I would update /etc/passwd to point to the new location instead. mrc

Re: Beowulf gone?
Down to it's basic, rendering videos is nothing more than a simple map-reduce, partioning a workload in a bunch of identical bits of processing. That could be done with N machines and a few simple shell scripts. Not really any need for anything fancy. What the fancier software gives you is stuff like automatic retries, fault tolerance, fancy ways of tracking the process of a job, and so on. But they likely require more management to maintain. Other reasons for a cluster might be web serving. You want to be able to handle some amount of queries per second with a reasonable latency for most of those queries. That may require you to scale in different ways. You need more machines to handle serving up the web content, a bit more to handle the various types of processing that needs to be done, some sort of scaling solution for your data store. Still parallelism, but each thing happening in parallel is likely a different type of task. A simple thing like Puppet or Chef could help you keep your machines in order. Maybe you don't need the computational power of a bunch of CPUs, but you need all of the memory for something? Maybe you need a bunch of machines with 128G of ram to look like a single machine with 1P of ram. So you need to have something specialized for moving bits around efficiently (either code to the data, or data to the code). Maybe you want to have different types of pipelines that do completely different things, and you want to make efficient use of the machinery you have. Say, you're doing both of the above, and during some hours of the day, you need more processing power to go towards web serving, you take away resources from you map-reduce. During off hours, you can let the MR have more processing power. Now you're dynamically trading off resources, and this is where some sort of clustering management might become useful. There is not likely to be any one solution for everyone. So no longer having anything exactly like Beowulf or some sort of direct replacement is not suprising. Likely stuff was learned from Beowulf and friends. Some things worked well, some things no, some things were never used, some things were needed. Folks take that experience and build new tools and systems. Old ones languish. And no direct replacement exists. Likely you need to break down what you really want to do, then look to see what solutions might work best for you, and experiment with the various ones, and see which one you like best. mrc

Two things. First, your du -sh * misses . files/directories. Depending on what's going on, that could be significant. I always use [du -sh .] myself. Well, strictly speaking, the . isn't necessary (at least with GNU df, not sure about others any more), but my fingers have been using that for years and it's ingrained. Second, on unix-like systems, it's possible to have a file open and deleted. It's common to do that with temp files, for instance. It could be that some process is running that still has a large file open, but there's no corresponding file name to find for du to find and account for, but df knows is still taking up space. Tools like lsof may help in cases like that. It has options to show deleted files. Though, personally, I tend to do something like: ls -l /proc/*/fd/* | grep deleted Mostly, because I learned that before lsof was written and I've never really bothered to learn the ins and outs of lsof. mrc -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

I used to do development on these devices 10+ years ago, I think for Tranz 330, 340 and 380, for precisely this type of operation. Looks like you're using much newer hardware. That said, when last I looked (and this was 10+ years ago), Verifone had no interest in supporting non-MS platforms for their development tools. All that we had was just the software to compile and load the software onto the device. It was a DOS command line program that worked only over the serial port. I don't remember if the cable were commonly available ones (my GF worked at RadioShack at the time and I don't remember ever seeing them in the store, and I hung out there quite a bit). Though, of course, one could probably always make one. I think I got the software to work once or twice under DOSEMU at the time, but since I had NT boxes as well, I just used those. I would suspect that running the CLI stuff under WINE these days might actually work fairly well. The language itself isn't that hard. Think of it as a language that looks like assembler, but acts like awk. It's terse, with a bunch of one letter commands, usually one per line, but operates on records separated into fields. For how we were using it, it worked quite well. Your biggest concern is how much memory you have on the device (the biggest differences between the models). We usually just aimed for the lowest supported hardware, trying to keep the app small, and just used the rest of the memory to store the clockin/clockout records. It looks like you can find the language manuals online at http://www.verifone.com/technical-support.aspx . You can at least look to see if you want to go down that route. >From reading that wiki page, it looks like Verifone might have more interest in supporting Linux, since they're using it inside the machines now. But I'm not sure about the availability of tools. I think when I moved on from that job, Verifone was trying to ramp down the sales of the software. I think you'd have to talk to your current vendor about getting the appropriate software. It's not obvious to me how they're connected to Verifone and might be using TCL. Assuming the old tcload stuff would even work on this new fangled device, you might be able to find someone who is willing to pass on their older license for something cheaper than what you can get it from PCS.

The message is still unread, just not associated with the Inbox label. If you go into Sent Mail, you'll find the message there, unread. When a reply comes in, the Inbox label is associated with the new message, not the whole thread. But it displays it as an entire thread. You should be able to show this by creating a new label, say 'testing'. Send a message to a list you subscribe to. As soon as you send, go into Sent Mail, and apply that new label.

Moore wrote: > > It's just that, in this case, I actually wanted aptitude to wipe half > my system, and I didn't realize I was preventing that by marking a key > package as a keeper. I solved this problem by doing it this way: I created a few meta-packages that just list the deps that I really want. They go: mrc-desktop mrc-laptop mrc-common Then host machine specific packages that depend on desktop/laptop as appropriate, and the corresponding kernels. Since I happen to use dselect (it was the first one I used and so I've stuck with it)., I would go in and do a normal upgrade. After that was done, and everything was up to date, I would do: [S]elect Scroll down to [Up to date installed packages] and use the <_> to schedule it to purge EVERYTHING off of my system. I then find the host specific package and reselect it, thus bringing back in just the stuff I want, and it's deps. Then I do an install. Sometimes I decide I don't want packages any more, so I remove them from my personal list of apps, and away it goes. This is much more interesting after a full install, where a good number of the packages then disappear. This is also useful if I did an apt-get install on a package to try it out. Sometimes I'll pull in a whole bunch of different tools to try things out, then later decide I don't like any of them. Ones I want to keep, I'll add to the appropriate metapackage. Otherwise, they'll get cleaned out the next time I do the above. I assume I could do similar with aptitude, but I've not yet bothered to learn it. I do find that keeping a metapackage around that lists what I want is nice for rebuilds though. I think it's easier than saving off selections. One thing I have run across that you might want to be aware of while you're cleaning out unused packages: Sometimes packages are broken in that multiple packages will use the same config files. If you remove one package, it takes the config files with it, breaking the other. So far the only one I've personally had that happen with is the ldap client stuff, and the bug about that has been open for a few years now. But, I wouldn't be surprised to find other packages might have similar issues. mrc -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

Re: lvm2 - question about pvmove
Don't try to do two things at once. If something goes wrong, you won't know which is the cause. Just put in the new drive and partition it into swap + lvm swapoff /dev/sda1 vi /etc/fstab # remove swap pvcreate vgextend pvmove -v /dev/sdb2 vgreduce /dev/sdb2 shutdown and remove the bad drive At that point, everything should be good and you can continue on. Moreover, you'll still have nearly 400G on the new drive that you can play with. Now you can lvcreate a new volume and move stuff over and set up mount points at your leisure.

It makes no sense to have multiple LVM partitions on the same disk, just to put them back together again as one big volume group. I mean, what's the purpose of using LVM in the first place then? No. Partition the disk into one swap + one LVM. Then use the LVM stuff to parcel out the space to various file systems. The only case that I could see for partitioning the drive into multiple LVM chunks would be if you want to experiment with using the LVM commands like pvmove and you only have one disk. For example, I have one machine with four disks, two 500GB and two 1TB. The partition schemes on those are: /dev/sda1 1 17 136521 82 Linux swap / Solaris /dev/sda2 18 121601 976623480 8e Linux LVM /dev/sdb1 1 17 136521 82 Linux swap / Solaris /dev/sdb2 18 121601 976623480 8e Linux LVM /dev/sdc1 1 17 136521 82 Linux swap / Solaris /dev/sdc2 18 60801 488247480 8e Linux LVM /dev/sdd1 1 17 136521 82 Linux swap / Solaris /dev/sdd2 18 60801 488247480 8e Linux LVM That gives me a VG of 2.73TB, which I have partitioned out into into a number of LVs of all sorts of different sizes: thune:~# lvdisplay | grep LV.Size LV Size300.00 GB LV Size128.00 GB LV Size70.00 GB LV Size5.00 GB LV Size512.00 MB LV Size16.00 GB LV Size1.00 GB LV Size14.00 GB LV Size1.94 TB LV Size20.00 GB LV Size25.00 GB Hmmm.. .

In my experience, find | cpio is faster than rsync for moving raw data around. Not sure why, but it feels that way. It's been a long time since I've done any speed tests. If I remember correctly, rsync will still use one process for reading and another for writing, so you end up reading gigs from disk, shoving gigs over pipe, writing gigs to disk. I'm not sure if that's still the case or not. The common tar cf - | tar xf - solution has the same issue. find | cpio just shoves the list of file names across the pipe, so there's nearly a third less data being moved around. Of course, all of that may be immaterial on modern machines. It may also be that find | cpio has less of the fragmentation issues that rsync does (see discussions in the week or two on this list).

I don't think .bash_profile gets sourced when you log in via an
XDM/GDM type session. (After all, when would it, since you don't
really have a login shell.)
Personally, I have it in my .bashrc, though that has it's own set of drawbacks.
If you do some searches about debian and sourcing login shells and
gdm, you'll find more than enough reading material to keep you busy
for hours.

That is how I started and how I've been, more or less, running with LVM for years, though I think I'm about to change. First, I've actually had different FS with different settings for different purposes. Mostly different bytes-per-inode for file system that have lots of big or lots of small files. Some have ext2 vs ext3 differences. Some are backups of retired windows machines that are just readonly. And i'd do the occasional snapshot to do backups from. As each FS would fill up, I would extend that particular FS. Some would reach a steady state. One interesting side affect of this is the fact that I would fragmentation at the filesystem level, as opposed to the file level. Every once in a while, I'd move LVs around to defrag (usually as part of adding a newer larger harddrive, and retiring the smaller one). One pain point I have is this: In order to run resize2fs(8), you have to fsck the FS first. As they grow larger and larger, this takes longer and longer. I have a 2TB FS now that I really don't want to grow any more because of that. Ext4 may solve the fscking issue, but in the one article I've read so far, resizing wasn't mentioned in it. (I'm also considering ext4 for other reasons.) One thing I do tend to do with every disk is this: I put a small swap partition on each disk, then the rest is an LVM partition. Depending on the machine, it could be 128M to 256M; I try to stay consistent across disks. I then set up each swap partition with the same priority. That way I get more spindles in action for swap. I have really no idea if it makes a difference or not, but it's something I do. It may very well actually cause more contention because if I'm doing something that is causing me to page, then I'm probably processing data on all of those disks anyway. Anyway, that's my experience with LVM. I like it, I've used it for, ... I'm not sure how long I've used it... has it been around for 10 years? I can't remember when I switched to it, but I'm pretty sure it was before I moved to the South Bay Area. It took for years of lobbying to get folks to start using it at work for one service I'm responsible for; down time for backups dropped from one hour to one minute, since they can now do LVM based snapshots and bring the service right back up. mrc -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

I would like to install Debian on my PQI 4 GB USB flash drive > but I am not sure which filesystem to use - ext2, ext3, XFS? I just grabbed a 4G USB and did my standard home install on it. I think I went with ext3, but after reading the rest of this thread, may change that. Some issues that I came across: I got confused during one installation and accidentally installed grub on my internal harddrive rather than the flash drive. Since this is a work laptop with an encrypted harddrive, wiping out the boot parittion made the primary system unbootable and had to reinstall that. Whoops. With my upgraded laptop, boot order changed from the time I booted from the install CD to to when I boot from the flash drive. I had to end up tweaking grub to point to the correct partition. I have some typical laptop issues that I think are not related to USB: had to install wired because I have to use non-free firmware to get wireless working, and since I run with /home mounted via NFS. Regularly my system tries to load the automount maps before wireless is up; I end up logging in as root once to reload them before logging in as my real user. Something to consider is: do you want swap on your flash drive or not? Don't you need swap in order to suspend? That could possibly speed up subsequent boot times. Personally I've not had success with suspend, but I can't remember right now if I set up swap on the flash drive or not. The biggest problem I have is, generally I'm using the flash in my laptop, and it sticks out quite a bit. I suspect I'll break it before I wear out the write cycles. If I ever come across the right CF or whatever media for a decent price, I might go ahead and purchase that, just so it's more internal the the system. The second biggest problem is the stupid thing flashes this bright blue light every once in a while, which is really annoying when the SO is trying to go to sleep. So, I'm running a laptop off of USB flash with /home mounted over NFS. It's not going to win any performance benchmarks, but I'm satisfied with it. mrc -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

Then appropriate packages will say they depend on flash-plugin rather than gnash explicitly. The whole conflicts between gnash/adobe flash issue that someone else brought up could be worked out later. Would it have been better if things went along the Provides route first?

That's essentially what MTP does (only without using an third location to sync against). Well, probably closer to using FTP to files to/from the device, only without using TCP/IP. (Oh, just refreshing and apparently one can run MTP over TCP/IP, though I suspect that implementations being talked about here are still direct USB connections.)

Re: shutting off screen blanker forever?
For xfce, you might try this: Settings Manager > Session and Startup > Application Autostart Scroll down and uncheck Screensaver. There may be additional things you need to do to make sure session stuff isn't loading screensavers through some other mechanism (i.e, squirreled away in a saved session or something). For that you might need to explicitly exit the screensaver (either through Settings Manager > Screensaver or a command line like xscreensaver-command -exit) And you likely need the xset stuff you already did on top of that. Of course, all of that is assuming you are using xscreensaver. ps -ef | grep screensave might be useful if the above doesn't work out for you. mrc PS: I dropped emc-users.

XFCE and automatic monitor detection
This is mostly a laptop question, but probably general enough that I want to post it here instead. So one thing that I think Gnome2 had over XFCE is better multiple monitor support. I could plug in a new monitor and the right thing would just happen. More importantly, I could unplug the monitor, and everything would automatically collapse down onto the laptop. Particularly useful if your screen is now locked. XFCE seems to have a different philosophy on this matter: use xrandr (or similar). Fine...OK... so rather than having to fire up arandr every time or a script (tough to do if your screen is locked and the password display is on the disconnected monitor), I'd like to have it happen automatically. So what kind of options do I have? Some searching seems to indicate that it's a matter of polling. Something akin to running xrandr -q every so often, and when a state changes, do something appropriate. There seems to be a hint that some sort of even could be fired and caught instead (via acpi, dbus, other assorted buzzwords), but that maybe it doesn't really work. Does there exist any software that I can just run at login time that I can configure such that ``when you see these particular monitors attached, switch into this mode.'' However it does that, I don't care as long as it doesn't bog down the machine. And ideally work if a monitor is unplugged when the machine is locked. If not, what would be my approach for writing something for myself? Thanks, mrc -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

bar();
}
$ gcc -Wall -Werror t.c
cc1: warnings being treated as errors
t.c: In function â:

Apparently every gcc-4.* has this same issue. gcc-3.4 does not.

autofs stopped working on testing
Has anyone else noticed that autofs has stopped working on testing? I'm really just digging into the debugging process, so may not have read all of the necessary docs quite yet. I've had autofs working for /home and a /share hierarchy for quite some time now, and haven't had too many problems with it. But the initial set up was long enough ago that I don't exactly remember the details of setting it up. I've had one machine that's been giving me grief and had to reboot daily for the last several days, so I'm pretty sure that the cause is the last day or two. I'm not seeing any packages, however, that look like they might have caused the problem. Nothing like slapd, glibc, autofs, nss or the like. Oh ... I just remembered... / on the ldap server was full, and I ended up nuking a lot of stuff on that partition. I wonder if I got overly zealous and deleted something important. I hope not. Anyway, the symptom is that no autmount maps are being seen: /etc/init.d/autofs start no automount maps defined.

ssh suddenly prompting for passphrase
Just sharing something that happened to me. After a recent upgrade with debian/testing, I noticed that ssh would pop up a window asking for my password, and this would be AFTER running ssh-add.

You can disable a specific component by removing the gnome-keyring-gpg and gnome-keyring-ssh elements from the startup applications. The interface depends on your session manager; for GNOME you can use gnome-session-properties. You can also simply edit /etc/xdg/autostart/gnome-keyring-*.desktop. """ Now for me, surprise GUI prompts are annoying for a couple of reasons. First, it's new. I've never seen that before this recent upgrade.

New automount (NFS) permission issues
I am running debian/testing across a number of machines, all mostly up to date (usually any given machine is no more than a week behind). Some time ago, maybe a couple of months, I started noticing some problems with my automounted NFS mounts, and wondering if anyone else has noticed something similar to the problems I'm about to describe. It's possible that I have something misconfigured that has worked for years, but now something is more strict. But I've been unsuccessful in finding anything in searches. And I'm not sure if this might be an autofs, kernel, or some other issue. Any suggestions on what kind of debugging to turn on would be helpful as well. The effect I'm seeing is: Immediately after boot, a normal user can access any NFS directory causing it to automount. After some amount of time though, after the mount is automatically unmounted, normal user can no longer do that, and instead root has to be used to access the directory (causing automount to remount). My configuration has not changed for a couple of years and has worked fine until recently. Each machine has a number of directories in /export that are exported via NFS. Most of these are configured for mounting into /share, though /home is as well. A typical exportfs entry looks like this: /export/images 192.168.1.0/255.255.255.0(rw,async,no_subtree_check,root_squash) The automount configuration is served up via ldap, and my configs there look like: dn: ou=auto.share,ou=automount,dc=mrc,dc=home ou: auto.share objectClass: top objectClass: automountMap dn: cn=/share,ou=auto.master,ou=automount,dc=mrc,dc=home objectClass: top objectClass: automount automountInformation: ldap:ou=auto.share,ou=automount,dc=mrc,dc=home --timeout=600 cn: /share dn: cn=images,ou=auto.share,ou=automount,dc=mrc,dc=home objectClass: automount automountInformation: thune:/export/images cn: images This seems to happen on both local (direct mounts) and remote (NFS mounts). Neither [autofs reload] nor [autofs restart] seems to help the situation once is gets into this state. One thing I've been doing as a temporary work around has been opening extra shells and dropping them into the directories I want to keep mounted. Sort of defeats the whole purpose of automounting, but such is the life of hacks. Also, I've recently been seeing problems with util-linux's flock(1) in my home directory. I use it as a serialization tool: $ cat bin/ser #!/bin/bash flock $0 "$@" And that has suddenly started failing with: flock: /home/nexus/bin/ser: Input/output error Which was quite scary at first (crap, /home is dying!) but is turning out to actually just be a constant NFS glitch. Not sure if related to the automount issue, but would not be surprising. I've scoured all of the stuff in /var/log with no luck. Does anyone see anything I have misconfigured above? Or extra configs I need to share? Any ``Yes, you need to read X as it explains a recent change?'' Any recommend flags to turn on for additional debugging? Anyone else seeing similar issues?

After a fresh boot, the follow both work with 2.6.32: $ ls /share/images $ ls /share/images/ With 2.6.39, the first always fails, and the second succeeds (that is the second succeeds if it's the first thing done after a reboot). mrc -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

Sounds like you may need to tune your filesystem. If fsync() is causing a problem, it probably means that it's forcing all pending data writes for that filesystem to disk, not just that file. Unfortunately this seems to be the default configuration because so many broken programs seem to depend on that. Sad really. A file system gets tweaked to make bad programs work well, then end up slowing down correct programs. So people break the correct programs to get around the performance problems and end up depending on the new feature of the filesystem. Personally, I tune all of my filesystems with journal_data_writeback enabled, and if any system apps break, I'll file bugs against them. But meanwhile, apps that do correctly use fsync() don't mess up performance for the whole system. As a compromise, you might try making your home directory (or whatever directory liferea keeps its data on) is configured with that mount option and see if it improves performance. Normally I'd point someone to this article: http://thunk.org/tytso/blog/2009/03/15/dont-fear-the-fsync but the site seems to be down at the moment. Fortunately, I ended up going into my RSS reader of choice, Google Reader, and finding the article and reshared it via my Buzz feed. I think you'd now be able to read it at: https://plus.google.com/117219624378904478730/posts/Mwn9a2woZYv Our of curiosity, why choose a local app over a central service like Reader or any of the others out there? I used to be a big fan of such local apps, but since I could be on any number of machines (2 home desktops, a couple of laptops, few machines at work), I've found a web app a lot more convenient. mrc -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

For my use case, in order to get the benefits for using ext4 over ext3, it worked better to create a new filesystem with ext4 and move all of the data onto it and them removing the old filesystem. mrc -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

Re: XFCE4 without panels
I just tried this in a VM and it seemed to work. >From a command line: xfce4-panel -q find ~/.config | grep panel Remove the xfce4-panel.xml (I also removed the empty directory just named panel.) The lack of panels seems to have survived a reboot. I don't know if it is sufficient for every variation involving saving session state or what not. But might get you started in the right direction. If worst comes to pass, you might be able to put the xfce4-panel -q command in a shell script that automatically launches when you log in. Good luck! mrc
Re: How can I find packages manually installed using "dpkg -i"?
Some tools I've been using lately are apt-mark and "dpkg-query --show".
The following UNTESTED commands (ran as a normal user):
(apt-mark showauto ; apt-mark showmanual) > apt-thinks-you-installed.txt
dpkg-query --show --showformat='${Package}\n' | grep -v -F
apt-thinks-you-installed.txt > rest.txt
The file "rest.txt" should have a list of packages installed that were
NOT installed via apt. With any luck, it is small enough to examine
manually.
You could do something like "apt list" to get a list of all packages
known by apt and see if you'd prefer to use just use the Debian
instead of Mint versions. And anything not in that list *probably*
came from other manual sources and you can do what you will with that
information.
You could poke around in /var/lib/apt/lists/ and see if the files from
the mint repos you used in the past are still there (I don't know if
they get cleaned up or not, might get lucky).
Regarding the comment in the thread about packages that the installer
added that show up as manual, you can do something like the following
to at least make apt think they were auto:
dpkg-query --show --showformat='${Package} ${Priority}\n' | awk '$2 ==
required {print $1}' > required.txt
sudo apt-mark auto $(apt-mark showmanual | grep -F required.txt) #
apt-mark will prompt, so you don't want to use xargs
Again, the above is untested, so verify first!
You might do the same for other priorities, like standard or
important. If for no other reason than breaking the list of packages
into smaller, digestible chunks that you can focus on. For example,
on my machine:
$ dpkg-query --show --showformat='${Priority}\n' | sort | uniq -c | sort -n
5 extra
29 important
29 standard
33 required
1472 optional
I could probably handle going through those smaller collections to
identify where they came from fairly easily. But that big optional
collection, not so much. For something like that, I might add
${Section} to the --showformat option, and divide them up that way.
Also, as a future project, you might consider creating metapackages to
help organize your installation. Again, for my machine:
$ apt-mark showmanual | wc -l
1
$ apt-mark showauto | wc -l
1563
I have a handful of debian control files that I use (base, desktop,
dev, serviceX, serviceY, machine1, machine2,...). The machine ones
depends on the services they host (NFS, LDAP, VMs), and whether they
need a GUI (desktop), whether I build on them (dev), or play games,
etc. Then each machine, after a base install I do something like:
apt-mark auto $(apt-mark showmanual)
apt install machineN
apt autoremove --purge
Of course, I monitor that autoremove to make sure it doesn't do
anything silly, and if it tries to remove a package I missed, I go add
it to the appropriate control file. My simple little way of doing
this is:
$ cat doit.sh
#!/bin/bash
for v in *.control; do
equivs-build $v > $v.log &
done
echo 'Waiting'
wait
echo 'Done waiting'
OUTPUT=/srv/deb/packages
rm -rf $OUTPUT
mkdir -p $OUTPUT
cp *.deb $OUTPUT
cd $OUTPUT
dpkg-scanpackages . > Packages
$ cat /etc/apt/sources.list.d/mrc-home.list
deb [trusted=yes] file:/srv/deb/packages ./
And yes, I should do better than the [trusted=yes].
Good luck on your upgrade!

Re: How can I find packages manually installed using "dpkg -i"?
Oops. The 'grep -v -F' should be 'grep -v -f'. Well, 'grep -v -F -f'
would probably be appropriate as well.
